pulseaudio log

The game uses MonoGame as the engine, it outputs audio via ALSA. Often, but not
every time, when I start the game the sound is played at double speed. What's
worse all other apps also start playing audio too fast, including paplay,
Chrome etc. Even those which are started after I exit the game. This can be
fixed by restarting PA or after killing all clients connections with paman (if
there are none after I exit the game, sound seems to be working correctly). I
believe no client should affect other clients like this, no matter how it's
broken. A friend of mine completed Transistor without such issues using PA. I
also found that something like this was long ago fixed in Wine but this game is
native. At least more native than pure Win32 apps+Wine and it doesn't use Wine.
It uses Mono though and FMOD as the sound engine.

My soundcard is CA0106 Soundblaster (SB0410 SBLive! 24-bit), CPU is Intel Core
i7-2600, 32Gb RAM, NVIDIA GeForce 770 GTX driver v340.65, Debian Jessie
GNU/Linux amd64, Awesome WM 3.4.15, kernel v3.16.

I also have another sound chip, ALC889 Analog. It's disabled in pavucontrol.

You can also see some ALSA underruns, I couldn't fix it no matter what
priorities and realtime priorities I set. They happen on both snd-hda-intel and
snd-ca0106.
